Reluctance Network Model of Switched Reluctance Motor Considering Magnetic Hysteresis Behavior

2021 IEEE International Magnetic Conference (INTERMAG), 2021
Quantitative analysis of the iron loss taking the magnetic hysteresis behavior into account is essential to development of high-efficiency electric machines. In previous papers, a novel reluctance network analysis (RNA) model incorporating a play model, which is one of the phenomenological models of the magnetic hysteresis, was proposed.

Integrated, variable-reluctance magnetic minimotor

IBM Journal of Research and Development, 1998
The use of lithography and electroplating to fabricate variable-reluctance, nearly planar, integrated minimotors with 6-mm-diameter rotors on silicon wafers is described. The motors consist of six electroplated Permalloy® horseshoe-shaped cores that surround the rotor. Copper coils are formed around each core.

3D Magnetic Reluctivity Tensor of Soft Magnetic Composite Material

2006 12th Biennial IEEE Conference on Electromagnetic Field Computation, 2006
Soft magnetic composite (SMC) materials are particularly suitable for construction of electrical machines with complex structure and 3D magnetic flux. For design and analysis of such 3D flux machines, 3D magnetic properties of the magnetic materials should be properly determined, modeled and applied for calculating the magnetic field distribution ...

Comparison of Reluctance and Surface Permanent Magnet Coaxial Magnetic Gears

2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020
The noncontact operation of magnetic gears offers significant potential advantages over mechanical gears. Reluctance magnetic gears (RMGs) have been proposed as an alternative to surface permanent magnet gears (SPMGs) at high speeds. This paper explains the operating principles of RMGs and provides a thorough parametric comparison between RMGs and ...

A permanent magnet‐assisted synchronous reluctance motor

Electrical Engineering in Japan, 2003
AbstractPermanent magnet motors have attracted a lot of attention recently for their potential for saving energy. However, they are only used for certain applications because the magnets are expensive. This paper discusses the optimum design of the low‐cost, highly efficient magnet‐ assisted reluctance motors with a minimum amount of magnets. The motor
